OnEntityVisibilityCheck

OxideCarbonEntity

Called when entity visibility check occurs.

object OnEntityVisibilityCheck(BaseEntity ent, BasePlayer player, uint id, string debugName, float maximumDistance)

Works — the game method in this build is the one the hook was written for.

Parameters

ent: BaseEntity
player: BasePlayer
id: uint
debugName: string
maximumDistance: float

Return value

objectThe returned value replaces the game result; null lets the game decide.

Example

object — you can affect the game: return a value to change or cancel the action.

private object OnEntityVisibilityCheck(BaseEntity ent, BasePlayer player, uint id, string debugName, float maximumDistance)
{
    Puts("OnEntityVisibilityCheck");

    // change nothing — the game continues as usual
    return null;

    // to affect the game:
    // return false; // your value instead of the game result
}

Works in both Oxide and Carbon: Carbon loads Oxide plugins as is.

Injection point
